Kentaro Yamamoto (played by Suzunosuke), who had been treated for cerebral hemorrhage in the past, was admitted to the hospital due to epileptic seizures.Because once he had a seizure, he was likely to have another seizure in the future, Yamamoto was prescribed anti-epileptic drugs.On the other hand, antiepileptic drugs are not recommended as prophylaxis in patients who have not had a single seizure.

It is said that Osako (Iura Arata) prescribed this medicine to Kawauchi Masaru (Sugisaki Hana) as a preventive medicine.Hearing this sentence, doubts about Kawauchi Masa's memory disorder emerged in Sanpin (Wakaba Ryuya)'s mind.Hoshimae (Chiba Yudai), who was entrusted by Tsuhata (Michiko Yoshise), asked Osako's subordinate Ayano (Okayama Amane) about what happened, but his doubts became deeper and deeper.
If Sanpin's idea is correct, then Osako told a “huge lie” to Kawauchi Masaru.Kawauchi Masaru couldn't believe that Osako had lied to him for a moment, but he found three bottles that proved his hypothesis and became angry.

At this time, Yamamoto began taking anti-epileptic drugs. In order to ensure adequate sleep, Yamamoto proposed to the company to reduce night shifts.However, the superiors, who lacked understanding of the sequelae, said that no special treatment could be given and that the daytime work should be taken off temporarily.Kawauchi Masaru made a bold move for Yamamoto.
